Overvoltage protection in single and three-phase voltage circuits [230 / 400V] 50 Hz.
The most important characteristic of Class 1 arresters is their ability to drain Iimp lightning current (pulse form 10/350 ms).
The devices in this series are intended for installation in zones 0A-1 in accordance with the concept of protection zones (IEC 61312).
- voltage protection level Up≤4,0 and 2.5 kV;
- patented sealed gas discharger and arc control pot;
- no blow hole - it is not required to keep the permissible distance to other devices;
- lightning current limit up to 100 kA (10/350 ms);
- V-shaped connection is possible;
- no leakage currents - possible installation before the counter;
- optional remote signaling contact (FM version);
